Product details

Overview

2SK3714-S12-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current DC-DC converter primary-side switching, motor drive H-bridge legs, and industrial SMPS applications. It delivers R_DS(on) = 13 mΩ max at V_GS = 10 V / I_D = 25 A, supports ±160 A pulsed drain current, and features built-in gate protection diode with 60 V V_DSS rating.

For engineers reviewing the 2SK3714-S12-AZ datasheet, 2SK3714-S12-AZ pinout, 2SK3714-S12-AZ application, or 2SK3714-S12-AZ equivalent, key selection criteria include low R_DS(on) at 4 V gate drive (22 mΩ max), avalanche energy rating (96 mJ), body diode reverse recovery time (46 ns), and isolated TO-220 thermal performance (R_th(ch-C) = 3.57 °C/W).

Technical Context

This discrete power switch operates in enhancement-mode with gate threshold voltage V_GS(off) between 1.5 V and 2.5 V, enabling robust turn-on under 4.0 V logic-level drive. Its 3200 pF input capacitance and 60 nC total gate charge support fast switching in hard-switched topologies up to several hundred kHz.

The device integrates a monolithic source-drain body diode with 0.94–1.5 V forward voltage at 50 A and exhibits single-pulse avalanche capability up to 31 A at 30 V, validated under standardized test conditions (T_ch = 25°C, V_DD = 30 V, R_G = 25 Ω).

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXTP50N055P	55 V V_DSS, 11 mΩ R_DS(on) at 10 V, TO-220 non-isolated package	Requires insulating washer for heatsink mounting; lower V_DSS limits 48 V bus margin	Prefer when cost sensitivity outweighs isolation requirement and 55 V rating suffices
IRF1404ZLPbF	40 V V_DSS, 4.7 mΩ R_DS(on) at 10 V, logic-level compatible, TO-220 isolated	Insufficient V_DSS for 48 V systems; superior R_DS(on) only beneficial below 36 V rails	Select only for 24 V or lower DC bus applications where ultra-low conduction loss is critical

Compared with IXTP50N055P and IRF1404ZLPbF, the 2SK3714-S12-AZ uniquely balances 60 V blocking, 4 V logic-level drive, and isolated TO-220 packaging-making it optimal for industrial 48 V power stages requiring mechanical isolation and avalanche ruggedness without sacrificing gate drive simplicity.

FAQ

What is the maximum continuous drain current rating for the 2SK3714-S12-AZ at 25°C case temperature?

The 2SK3714-S12-AZ has a maximum continuous drain current (I_D(DC)) of ±50 A when the case temperature is maintained at 25°C. This rating assumes proper heatsinking and is limited by the device's 35 W total power dissipation (P_T1) at T_C = 25°C. Derating is required above 25°C per the datasheet's thermal curves.

Does the 2SK3714-S12-AZ have a built-in gate protection diode, and how should it be used in circuit design?

Yes, the 2SK3714-S12-AZ integrates a gate-to-source protection diode to guard against ESD damage during handling and assembly. However, Renesas explicitly states that this internal diode is insufficient for operational overvoltage protection. External gate clamping (e.g., Zener diode to source) remains mandatory if transient voltages exceeding ±20 V may occur during normal circuit operation.

Can the 2SK3714-S12-AZ be driven directly by a 3.3 V microcontroller GPIO without a gate driver?

The 2SK3714-S12-AZ specifies R_DS(on)2 = 22 mΩ maximum at V_GS = 4.0 V and I_D = 25 A, confirming functional operation at 4 V. While a 3.3 V GPIO falls slightly below this threshold, actual R_DS(on) remains usable for moderate currents (<10 A); however, full 25 A performance requires ≥4 V drive. For robust 25 A switching, a level-shifting gate driver is recommended.

What is the thermal resistance from channel to case (R_th(ch-C)) for the 2SK3714-S12-AZ, and how does it impact heatsink selection?

The 2SK3714-S12-AZ has a specified channel-to-case thermal resistance (R_th(ch-C)) of 3.57 °C/W. When combined with a heatsink's R_th(c-a) and ambient temperature, this value determines maximum allowable power dissipation. For example, at T_A = 50°C and desired T_ch ≤ 125°C, total allowable R_th(c-a) is ~17.4 °C/W - guiding heatsink size and forced-air requirements.

Is the 2SK3714-S12-AZ suitable for automotive applications, and what quality grade does it carry?

The 2SK3714-S12-AZ is classified as a "Standard" quality grade device per Renesas documentation, intended for computers, office equipment, industrial robots, and communications gear - not automotive or safety-critical systems. It lacks AEC-Q101 qualification and is not rated for "High Quality" transportation applications. Use in automotive contexts requires explicit Renesas written consent and additional validation.
